ltors, of which the following is a specification.

This invention relates to ozone generators and has for its object the provision of a simple effective and reliable mea-ns for producing and collecting ozone. I

A further object of the invention is to provide in an apparatus of the above mentioned character a novel means for neutralizing the heat generated by the electric currentl employed. f l

A further obj ect of the invention is to provide in an apparatus of the above mentioned character a means whereby any one of the several units employed may be replaced without affecting the operation of the several remaining units.

Other objects and advantages of the invention will be apparent during the course of the following description taken in connection with the accompanying drawings.l

In the drawings, forming a part of this specication and wherein like numerals are employed to designate like parts throughput the same,

Figure 2 is a side elevation of a unit of the apparatus, the unit being shown partly in section,

Figure 3 is an enlarged fragmental sectional view of a wall of a unit,

- Figure 4: is a horizontal sectional view taken on line lri of Figure 1,

Figure 5 is a horizontal sectional view taken on line 5.-5 of Figure 2, Figure 6 is a modified form ofa cooling system, and,

Figure 7 is a modied form of a unit.

In the drawings, attention being called to Figures 1 to 5 inclusive wherein is shown one formY of my invention the numeral 10 indicates a base or supporting means for the apparatus as a whole.- Upon the base 10 there is arranged a plurality of pipes 11 having connection with a common pipe 12 through which Vair is forced by any suitable means, not shown, into the apparatus as a whole, the function of which air will be more elaborately discussed hereinafter.

Upon each of the pipes 11 there is arranged an elongated hollow support 13 formed from a suitable insulating material. rllhese supports, as clearly shown in Figure 2, communicate with the pipes 11 and areeach adapted to support and communicate with theinterior of a hollow rectangular unit 14. The units 14 are each provided with walls 15 and are `further provided at the top with a/plu" rality of openings 16. These units are constructed from electrical conducting material but are provided upon Ytheir `walls with a Aducting pipes 19 which extend horizontally through the units as clearly shown in Figure 4- and connect with an ozone collecting pipe A2O through which thel ozone is conducted to asuitable container, not shown. Upon each of the units provided with the insulating inateriall? there is arranged an insulating fuse switch 22, the upper end of which is adapted to bev removably retained in engagement with an arm 23 suitably connected to the top wall of the unit. To the switch 22 at its pivotalend there is connected an electrical conductor 24C which in turnV is yconnected to a main line 25, the main line being in circuit with a generator indicated dia! grammatically at .M and grounded as shown at G. Within the main line 25 there is interposed a suitable manually operated switch diagrammatically indicated at S. Upon each of the units adjacent those units whichV are provided with insulating material 17 there is disposed a switch 22 connected to the unit identically with the switch'. 22 hereinbeforc described. The switches 22 are inl turn connected by means of conductors 251 to a main line 25 which is grounded as shown at G.

ln considering Figure @wherein is shown a modified form of a unit cooling means it is to be understood thatthe electrical connections employed and the principal of operation of the unit electrically is the same as that of the units, the construction ofwhich is hereinbeforc described but instead, howextend transversely vblock 21 to which is pivotally connected :a

ever, of employing the air supply pipe 12 together with its various co-operating elements I desire to employ a local means and to this end I provide a plurality of walls 15 Vwhich are arranged within the unit 14 and spaced alternately from the top and bottom of the unit. To one end of the unit as shown at 26 there is connected a pipe 27 through which oil may be forced by means of a pump as shown at P, which oil is elevated to a suitlable point above the unit Vand deposited through a nozzle 28 into a funnel 29 which extends downwardly an appreciable distance into the unit as clearly shown. By this arrangement I dispense with the use of air as alcoolingmedium for the several units and substitute therefor a unique system whereby oil maybe employed to accomplish this end.

In considering Figure 7 wherein is shown a modified form of the invention, I desire to mount each of the units 14 upon an insulating base 30. I find, however, that by employing oilas shown at 31 together with electrodes 32 I attain a highly satisfactory result in that the oil being of a nonconducting character serves as a means to retard the passage of the electric current, thus enabling me to employ a very thin coat of insulating material 33 as compared with the coat of insulating material as shown at 17. In this instance I prefer to `use insulating material such as a nonconducting varnish or enamel having as one of its constituents such material as bakelite, condenste, etc. I find further that the discharge between the units 14 is not so likely to fiow locally but rather on the other hand, tends to dis` charge evenly over the total area of a side of the unit. The electrode 32 is connected with a suitable insulating cap 34 which is mounted upon the unit 14 as clearly shown.

The electrodes 32 are further connected with astem 35 which in turn is connected with a terminal 36,- the terminal being adapted for connection with a fuse switch identical with the switch 22 hereinbefore described. Itis `to be understood thatthe same system of wiring as shown in Figure 1 may be incorporatedand used in connection with the modified form of my device shown in Figurel 7. It -is to be further understood that I do not wish to -limit myself to any specific means such as I have described in connection with Figure 6 for supplying the oil indicated. by the numeral 31 tor the various units 14". But on the otherhand, it is to be understood that any system suitable may be employed for conducting the oil to the units 14, which oil is intended to serve not only as a` mea-ns for cooling the various units but also as a means for retarding the flow of current through the device as a whole and further as a means for evenlyy distributing the electrical energy over the entire area of a given side of a given unit.

The operation of the device as shown in Figures 1 to 5 inclusive is as follows: Air is forced into the various units 14 through the pipe 12 and expelled at the top through the various openings 16 which tend to keep the'appaiatus at a norma-l or substantially uniformV temperature during its operation. By closing the switch shown at S current is supplied through conductors 24 and their respective units whereupon the electric energy is transmitted to the sides ofthe units. The electric current then, due to its eXcessive E. M. F., passes through the insulating material 17 to the adjacent units 14 passing onwardly through the conductors 24 and 25 as is apparent.

ozone is formed between the units, which ozonel is drawn off through the pipe 2O by means of a suitable vacuum pump or the like not shown, the ozone being in turn stored or confined within a suitable container also not shown- Due to the fact that the pipes 19, connecting the pipe 20 with the conduits 18, are confined within the units 14 the ozone passing through these pipes is necessarily cooled by the air currents forced into the apparatus. through pipe 12.

In considering the modified form of the invention shown in Figure 6 it is to be understood that the operation of the device electrically is substantially the same as that described in connection with Figures 1 to `5. Instead, however, of employing air currents forced through pipes 12 as a means for cooling the apparatus I desire to use a suitable oil which is continuously passed through each of the units 14 in the direction of the arrows by means of a suitable l pumpl as indicated at P, the oil being used over and over as a cooling medium.

In considering the modified form shown in Figure 7 it is to be understood in this connection that the operation electrically of the device is substantially the same as that hereinbefore described in connection with Figures 1 to 5 inclusive; Instead of using a vcomparatively thick sheet .of insulating material as shown at 17 I am able to employ a relatively thin sheet Vof insulating varnish the principal constituents of which have hereinbefore been mentioned. This is made possible due to the fact that theI oil 31, through which the electrical energy must necessarily pass to reachan adjacent unit, retards the {iow of electricity and at theV same time tends to and does evenly distribute the discharge over the entire area of a side of the unit, thus eliminating the objectionable feature of localization of v-a discharge.

In both of the formsY of my invention shown in Figures 1 and 7 I desire to employ a fuse switch 22 which may be of any con ventional type in order to open the circuit automatically of any given unit should a short circuit for any reason take place.

It is to be understood that the forms of my invention herewith shown and described are to be taken as preferred examples of the same, and that various changes in the shape, size and varrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, what I claim as new and desire to secure and protect by Letters Patent of the United States, is:
